load average
we have an unix system which has
load average normally about 20.

but while i am running a particular unix batch which performs heavy
operations on filesystem and database average load
reduces to 15.
how can we explain this situation?

while running that batch idle cpu time is about %60-65
while not running idle cpu time is about %70-80

how can i check swap status to determine if there is
a bottleneck or not?

NAME

       Sys::Statistics::Linux::LoadAVG - Collect linux load average statistics.

SYNOPSIS

DESCRIPTION

       Sys::Statistics::Linux::LoadAVG gathers the load average from the virtual /proc filesystem (procfs).

       For more information read the documentation of the front-end module Sys::Statistics::Linux.

LOAD AVERAGE STATISTICS

       Generated by /proc/loadavg.

	   avg_1   -  The average processor workload of the last minute.
	   avg_5   -  The average processor workload of the last five minutes.
	   avg_15  -  The average processor workload of the last fifteen minutes.

METHODS

   new()

	   my $lxs = Sys::Statistics::Linux::LoadAVG->new;

       It's possible to set the path to the proc filesystem.

	    Sys::Statistics::Linux::LoadAVG->new(
	       files => {
		   # This is the default
		   path    => '/proc',
		   loadavg => 'loadavg',
	       }
	   );

   get()
       Call "get()" to get the statistics. "get()" returns the statistics as a hash reference.

	   my $stat = $lxs->get;
